The Sudo extension the ability for Sudoers on the wiki to login to other users' accounts, using "Special:Sudo".
This may be used for helping users set their own preferences, testing to see if something in the UI is affected by their login, or changing things under their name.

Sudo does log use of sudo to transfer to another user's accounts, however beyond that there is no tracking of what the sudoed user does.
Be careful who you give sudo to as it can be abused in the worst of ways.
